Abstract

A fabric web intended for the production of garment inserts for reinforcing shoulder, chest or lap parts of garments the web having a reinforced region comprising a double-cloth formed by two fabrics, each having a warp thread and a weft thread system, and a reinforcing thread warp or weft system between the two fabrics, the reinforcing threads having a stronger spring force than the warp and weft threads of the two fabrics. Threads of a fabric are interlaced with threads of the other fabric and/or reinforcing threads are interlaced with fabric threads. The physical characteristics of at least one system, e.g. spring force of the reinforcing threads or thread spacing or density, vary in a direction transverse to the length of the threads of such system to provide a spring force and resilience which varies across and/or along the web from the reinforced region toward another portion of the web.

Description

The invention relates to a fabric web with adjacently disposed reinforcing regions of different resilience and spring force for the production of inserts cut therefrom for the shoulder, chest and lap reinforcement of garments, said inserts having the maximum resilience and spring force in the insert region intended for shoulder reinforcement and comprising a double fabric at least in this region.

Fabric webs for the production of inserts cut therefrom have already been proposed which comprise gradually springy reinforcement regions with maximum resilience and spring force in the insert region intended for shoulder reinforcement of garments, which reinforcement regions are adjacently disposed in the warp direction and contain in this region a double fabric comprising two fabric webs each having two warp thread and two web thread systems which are loosely and floatingly joined to each other through weft threads. In the reinforcement region comprising the double fabric the inserts cut therefrom have a volume which is substantially larger than that of the remaining regions with a single fabric so that passage of heat accompanying the ironing of the fixing inserts cut therefrom and coated with hot-sealing adhesive is obstructed to a much greater extent in the two-layer fabric region than in the remaining single-layer regions.

Abrupt changes of thickness occur at the line of transition from the single-layer to the double-layer fabric system, which leave impressions on the exterior of the garment in the course of ironing. Dressing and coating with hot-sealing adhesive also entail distortions and folds on either side of the transition line, which can become visible as additional impressions on the exterior of the material when the latter is ironed. Different shrinkage characteristics are also observed. The differences in heat passage result in different drying and sintering of the adhesive in the course of coating and in differences in adhesive action when the insert blanks are ironed. On the other hand, the better quality of textile feel compared with other inserts available on the market, which have graded reinforcement regions, cannot be denied so that there has been no lack of comprehensive approaches to develop reinforcing inserts with double-fabric regions to a stage suited for production and processing. The majority of the presently marketed kinds of inserts is unsatisfactory because they still require additional shoulder and chest padding by insertion of a traditional horse-hair canvas and a traditional shoulder support, and because they do not satisfy the requirement of the producers of ready-to-wear garments for a single insert which combines all the necessary reinforcing and padding functions.

The invention is based on the problem of providing a fabric web with reinforcement regions of different stiffness and comprising, at least in the most springy region of the web, a double fabric and is capable of being inserted as a sole insert into garments without additional inserts such as canvas or the like. Furthermore, the abovementioned disadvantages are to be substantially or completely avoided. According to the present invention this is accomplished in that a second warp thread or weft thread system is embedded between the two fabric inserts of the double fabric inserts of the double-fabric region, each comprising a warp thread and a weft thread system, the individual threads of the second system having a greater spring force than the warp or weft threads of the top and bottom fabric.

The second reinforcing thread system in the warp or weft direction can be embedded as a plain filling warp or a plain filling weft between the two fabric layers without interconnecting the two layers. In this case it is desirable for the warp or weft threads of the top and bottom fabric or weave to intermesh comparatively frequently so as to produce a connection bewteen the top and the bottom weave. Advantageously, however, the second reinforcing thread system interconnects the two fabric layers in the form of an interlacing warp or an interlacing weft by alternate engagement with the top and the bottom fabrics. It is also possible that several or all of the possible types of weave are combined in the reinforced double-fabric region of the inventive fabric web.

For better understanding various embodiments of the fabric web according to the present invention will be described in the following with reference to the accompanying drawings wherein:

All features explained in the description are of significance for the invention. Therefore they are also claimed for the invention even if they are not stated in the attached claims.

A corresponding, reinforced double fabric zone is illustrated in FIGS. 1 and 2. In this illustration the crossing points of all warp and weft threads of a weave pattern repeat are marked. The pattern repeat which adjoins horizontally or perpendicularly has the same weave pattern. The portions a₁ through a₆, b₁ through b₆, and c₁ through c₆, which are situated in the horizontal rows, are symbols of the weft threads whilst the portions o₁ through o₆ and u₁ through u₆, which are situated in the vertical rows, are symbols of the warp threads. The portions of the horizontal rows, which are designated with numeral a, represent the weft threads of the back cloth or fabric (= back weft) whilst those designated with numeral b refer to the weft threads of the embedded filling (packing) or binding weft, and those designated with numeral c represent the weft threads of the facing cloth (= facing weft). In the vertical rows the hatched portions designated by numerals u₁ through u₆ are the warps of the back cloth (= back weft) and the non-hatched portions designated by numerals o₁ through o₆ are the warps of the facing cloth (= facing warp). In several ones of the portions markings are entered. The marking symbols within the rows a, b or c correspond to each other. Each portion marking hence refers to a point of intersection of warp and weft threads, however with the proviso that at this point the associated warp thread bears on top of the associated weft thread. The points of intersection of back wefts with warp threads on top are situated in the horizontal rows a₁ through a₆ and are marked there in the portions by the numeral X. The numeral O denotes points of intersection of face wefts with warp threads on top, whilst the symbol denotes points of intersection of packing or binding wefts with superimposing warp threads. The particular warp thread is placed on top is defined by the coordination to the vertical rows o₁ through o₆ and u₁ through u₆. Finally, the empty portions without markings indicate that at these points the respective weft thread is situated at the top and covers a warp thread placed underneath. The particular warp thread covered by a particular weft thread is in turn defined by the association with the horizontal and vertical rows, but in this case of the free portions.

For example, the marked and unmarked zones of the bottom horizontal row a₁ in FIGS. 1 and 2 have the following significance from left to right:

o₁ bears on a₁ ; u₁ is positioned underneath a₁ ; o₂ bears on a₁ ;

u₂ bears on a₁ ; o₃ bears on a₁ ; u₃ bears on a₁ ;

u₄ is positioned underneath a₁ ; o₅ is disposed on top of a₁ ;

u₅ bears on a₁ ; o₆ bears on a₁ ; and u₆ bears on a₁.

From the weave patterns of FIGS. 1 and 2 the cross-sectional patterns with the schematic sketch of the weft threads can be easily obtained to produce a plastic image. The cross-sectional views, too, are designated by numerals a₁ -a₆, b₁ -b₆, c₁ -c₆ and u₁ -u₆ and o₁ -o₆. The extension of the reinforcing weft b₁ shows that the said weft thread is simply an inner packing weft which engages neither with the warp threads of the face cloth nor those of the back cloth and hence does not perform any binding function. On the other hand all reinforcing weft threads b₂ through b₆ engage with the face cloth and back cloth where they alternately surround face and back warp threads. These reinforcing weft threads connect the face cloth to the back cloth. A sole connection between face and back cloth by a reinforcing weft thread is accomplished by the binding weft thread b₂ which binds one of the three face and back weft threads. The remaining fabric cross-sectional views illustrate that also weft threads of the face and/or back cloth engage with the warp threads of the back and/or face cloth, so that an additional binding between face and back cloth is achieved. A particularly intimate binding can be seen in the cross-sectional illustration a₄ b₄ c₄ where face cloth and back cloth intermesh and where the reinforcing binding weft interlaces all warp threads of the face cloth and back cloth.

The weave pattern illustrated in FIGS. 1 and 2 shows a reinforced double cloth region with twill interlacing with visible twill line on both surfaces.

The insert web which is provided with this reinforced double cloth weave can preferably be materialized as a so-called weft variation such that the regions with the reinforced double cloth weave are repeated in the warp direction. These repeated reinforced regions are thereby produced by a variation of the weft threads whilst the warp threads remain unchanged over the entire length of the web.

The insert blanks 4 are cut out in the longitudinal direction from the above-mentioned fabric web, as is illustrated in FIG. 16. Substantial transverse regions 2 of reduced spring force are situated along the longitudinal extension of the fabric web between the repeating transverse reinforced double-cloth regions 1.

The fabric stiffness should vary continuously if possible. To this end the transverse zones of the reinforced double-double cloth region 1 is followed by a transition region where the springy intermediate reinforcing weft threads are successively replaced by weft threads having less spring force. This can be followed by a plain double-cloth region comprising two warp thread systems and two weft thread systems respectively, and then by a single-ply fabric with one warp thread and one weft thread system, e.g. a fabric in the known cross-twill weave. In this case it is advantageous to provide for thickness equalization at the transition by the employment of a more voluminous weft thread system in the cross-twill fabric region.

The single-ply double-cloth region adjoining the reinforced double-cloth region can have a weave, for example, such as that sketched in FIGS. 3 and 4.

Sequences other than the above-mentioned weave sequence can also be selected. For example, a direct transition from the double-cloth transition region with less springy intermediate weft to the cross-twill weave is possible, and in this case, too, thickness equalization can be accomplished by using a more voluminous weft thread system in the cross-twill region. Finally, it is also possible to dispense entirely with a change of weave and to provide the double-cloth region with an additional weft thread which has a graded spring force and extends over all reinforcement stages.

A single-ply fabric with cross-twill weave in the intermediate regions can also be substituted by a double-warp weave comprising two warp thread systems and one weft thread system.

It is also possible to select simpler kinds of weave which comprise a double cloth with embedded reinforcement threads instead of the comparatively complicated double-cloth weave with reinforcement weft threads as illustrated in FIGS. 1 and 2. The reinforcement threads can be weft threads as well as warp threads, and finally it is possible to achieve transitions to the less springy regions of the insert web by means of these simpler weaves, which transitions elegantly rise and fall entirely smoothly and homogenously and which in terms of the weave can be derived directly from each other by addition or omission of thread systems.

Such insert web comprises, for example, in the reinforced double-cloth region the weave pattern of a weave pattern repeat as illustrated in FIG. 5. In the weave pattern which is constantly repeated horizontally and vertically in the fabric, the horizontal rows designated by numerals a, b, or c represent again face wefts, back wefts and intermediate reinforcing wefts in the case of an insert web woven as a weft variation. The intermediate wefts are binding wefts which alternately interlace the face cloth and the back cloth. There is no additional interlacing between the face cloth and the back cloth. The vertical rows o and u are the face and back warps of the weft variation. The cross-sectional view shown in FIG. 6 illustrates the extension or the course of the weft threads a, b and c whilst in FIG. 7 the course of both warp threads o and u is illustrated.

The insert web, which cannot only be produced as a weft variation but also as a so-called warp variation, also has the weave pattern shown in FIG. 5, but in this case the horizontal rows a, b and c of the weave pattern are face, back and intermediate reinforcement weft threads while the vertical rows o and u are the face and back wefts of the warp variation. In this case the cross-sectional view of FIG. 6 illustrates the course of the warp threads a, b and c while the cross-sectional view of FIG. 7 illustrates the course of the two weft threads o and u.

In the warp configuration the weft threads remain unchanged over the entire length of the web and the grading of the reinforcement regions is accomplished transversely to the web by variation of the warp threads.

FIG. 15 shows the arrangement of the reinforced double-cloth region 3 in the middle of the web. The less stiff fabric regions 5 are situated on both sides of the web, from which the inserts are cut out transversely to the web. This illustration shows a mirror-image fabric web from which two insert blanks 4 can be cut out in the transverse direction through a nesting and material-saving arrangement. This insert web can also be made avaiable to the processor in a width which allows only one insert to be obtained in the transverse direction. It is also possible to arrange the reinforced double-cloth regions 3 on the edges of the double-width web.

In the webs illustrated in FIGS. 15 and 16 according to FIGS. 5 to 7, the reinforced double-cloth regions 1, 3 are adjoined by transition regions derived from the fabric of said double-cloth regions, which in the case of a warp variation are adjoined by a warp doubling region and in the case of a weft variation by a weft doubling region which is intended for the least springy lap reinforcement in the cut-out insert. The associated weave pattern is illustrated in FIG. 8. The cross-sectional views in the longitudinal and transverse direction of FIGS. 9 and 10 show that the double weave of FIG. 8 is derived from the weave of FIG. 5 by omission of the thread systems a and c.

From the fabric cross-sectional views in FIGS. 12, 13 and 14, which approximately also illustrate the relative spacial arrangement of the thread systems, a three-dimensional view of all grad-ed regions is obtained.

In the example illustrated in FIG. 12 the fabric web comprises a reinforced double-cloth region 1, 3 with the same density of the warp or

weft threads

8, 9, 10, 11 of the face, back and reinforcing warp thread systems or of the face and back reinforcing weft thread system. This region is adjoined by a transition region in which the density of the warp or

weft threads

8, 9 of the face and/or warp or of the face and/or weft is reduced and where the springy reinforcing warp or weft threads 10 are replaced, initially partially and then in their entirety, by less springy reinforcing threads 11, followed by a further region 2, 5 without face and back warp or

weft threads

8, 9 in weft or warp double weave. The weft or warp threads of the face and back cloth, which are transverse thereto and correspond to the threads o and u in FIGS. 1 through 10, are designated in the present illustration by

numerals

6 and 7.

The warp or weft thread density of the face and back warp or of the face and back weft can be uniformly reduced on both sides of the fabric as is illustrated in region 12 in FIG. 13. In this case the warp or weft density of the face and back

warp

8, 9 or of the face and back

weft

8, 9 is always the same on opposite locations of the fabric. But it can also be asymmetrical and in an extreme case in such a way that on one side of the fabric the face warp or face weft threads 8 or the back warp or back weft threads 9 are removed either partially or wholly. FIG. 14 illustrates such a transition 13 to the double weave in which the face warp threads 8 in a warp variation or the face weft threads 9 in a weft variation are absent initially in part and then in their entirety. In the region with back warp or back weft threads 9 and the missing face warp or face weft threads 8 the corresponding fabric region is a double cloth comprising two fabric plies each having one warp and one weft thread system.

The illustrated weaves and weave transitions according to FIGS. 8 through 14 permit accomplishment of a particularly high degree of uniform fabric thickness by selecting suitably different yarn thicknesses in the reinforcing or binding thread system, which feature is of particular significance when the inventive insert web is woven as a warp variation because otherwise the weaving, dressing, coating and coiling into reels ready for shipment would be difficult or hardly feasible. The spring force between the reinforced double-cloth region for shoulder reinforcement and the non-reinforced springy double region for lap reinforcement can in practice vary continuously in the same fabric web in the region of very high resilience to the region of soft and woolly fabric characteristic of the fabric. To this end, yarns with large-gauge fibers are employed predominantly for the reinforced double-cloth region and in the adjoining less strong regions they are replaced, initially in part and then in their entirety, by yarns with less coarse or with fine fibers.

The fine fiber materials mainly comprise regenerated cellulose fibers with a fiber gauge of less than 6 dtex and preferably between 1.5 and 4.0 dtex, but also synthetic fibers, e.g. fluffy polyacrylonitrile fibers. The springy reinforcing threads can consist of yarns or twined yarns of coarse endless synthetic fibers. The twines can be produced by serving or doubling with fine cotton or cellulose threads. Preferably multi-fill yarns of regenerated cellulose or cellulose esters are employed as endless synthetic yarns, which comprise approximately 5 to 25 individual fibers with a fiber gauge of approximately 20 to 150 dtex. Also endless yarns of synthetic polymers, such as polyamide or polyester, can be used. Finally, the reinforcing threads can also comprise yarns or twines containing human or animal hair. In the latter case the yarns or twines should be protected against hair migration by treatment with a binding agent.

The face and back warp and weft threads of the reinforced double cloth region and the adjoining transition region generally consist of fiber material which is finer than the reinforcing threads of the reinforced double-cloth region. These threads can consist predominantly or exclusively of yarns or twines of cotton or regenerated cellulose. Whilst the fiber grade of cotton is determined by nature and ranges between 1.2 and 2.4 dtex the fiber grade of the regenerated cellulose fibers can be selected again from the above-mentioned range of below 6 dtex approximately, and preferably from the range from 1.5 to 4.0 dtex.

The weave pattern which is visible mainly on the fabric face and back sides should be preferably the weave pattern of a cross-twill weave in the reinforced double-cloth region. The weaves according to FIGS. 8 through 14 produce such a weaving pattern although they can also be replaced by weaves with a different weaving pattern. The cross twill weave of the face and back cloth and the double weave can be derived from the weave patterns and the fabric cross-sections, and in this context the warp and weft threads of the face cloth on the top of the double-cloth region and the warp and weft threads of the back cloth on the underside of the double-cloth region with an additional reinforcing warp thread system produce the weaving pattern of a warp cross-twill weave in which the warp threads float over several weft threads, for instance three weft threads according to FIGS. 5 to 7, and therebetween place the weft thread in a cruciform offset configuration beyond a point of intersection on the surface of the face or back side of the cloth. Accordingly, the weaving pattern of a weft cross-twill weave is produced by the warp and weft threads of the face cloth on the top side and by the warp and weft threads of the back cloth on the underside of the double-cloth region with additional reinforcing weft thread system, in a configuration in which the weft threads float over several warp threads, for instance three warp threads according to FIGS. 5 to 7, and therebetween place the warp thread in a cruciform offset configuration beyond a point of intersection on the surface of the face or back side of the cloth.

In the double region where the face and back cloth is missing, the cross-twill weave according to FIGS. 8 to 11, namely, the weft cross-twill weave on the top and the underside, also appears if the reinforced double-cloth region shows a warp cross-twill weave. In this case the double interlace is a weft double weave. Conversely the warp cross-twill weave appears in the double region on the top and the underside when the weft cross-twill weave appears in the reinforced double-cloth region. In this case the double weave is a warp double weave.

The embodiment of the inventive fabric web as shown in FIG. 12 can, for instance, be readily modified within the scope of the invention if the back warp or back weft threads on the left side in FIG. 12 are woven-in over the entire web surface and are not removed so as to produce a completely uniform weaving pattern on one fabric web side. Preferably this side of the fabric is used to apply the textile hot-sealing adhesive.

Finally, the fabric web can also be varied by a change of the weft and warp density from fabric region to fabric region and within the regions themselves.

When the weaving step is finished the inventive fabric web is processed as usual and is subjected to high-quality finishing and anti-shrink dressing. Dressing of the fabric web results neither in distortion nor folding.

The fabric web is intended mainly for so-called front fixing in which the insert blanks are joined to the outer cloth of garments such as jackets, costumes, coats, by ironing. To this end, the fabric web is provided with a continuous layer of a hot-sealing textile adhesive which is preferably applied in a dot-raster arrangement to one side of the fabric web.

The total insert length and the length ratio of its different reinforcement regions relative to each other depends on the garment into which the insert is to be placed. In the case of a jacket the average insert length is approximately 83 cm to 87 cm. In fabrics of the weft variation, approximately the same insert pattern repeat length should be provided in the longitudinal direction and in fabrics of the warp variation approximately the same or twice the fabric width should be provided. Compared with inserts for jackets the inserts for coats usually have a somewhat shortened chest part and a lengthened lap part, which is influenced by fashion and must therefore be woven in a suitably modified form.

Inserts of the fabric web according to the invention in their entirety provide very springy and resilient reinforcements in the shoulder and chest regions, however with a flowing texture without having a stiff board-like feel which is reduced elegantly and with a homogeneity not accomplished up to date from the shoulder region downward and which in the lap region has a bulky-soft characteristic which leads to optimum wearing comfort. Additional inserts such as canvas pads or shoulder pads can be omitted.
